Fig. 3 is a rear view of the stopmechanism applied and Fig. 4- is a sec- 'tional view taken upon the.line 4-4 of Fig. 3.

Referring .now more particularly to the drawings, 1 designates a diskplaying graphophone of. the usual well known construction, the, box ofwhich is provided at its rear with -a horn and reprodueer arm supportingbracket 2. The swinging reproducer supporting arm 3, being pi'rotall ysecured at one end to the bracket- 2, carries at.- itsfree end-areproducer 4, which may he of any In manufacturing the improved.stfllimechanism with the air-whines, it-may be found convenient to mount themechanism directly upon the top or woodwork of the;

I andmay be securedto the top' of the graph-' graphophone, but as aseparate article ot -manufacture a plate is employed to support themechanism. The supporting plate is indicated 'at"7 ophone in anysuitable manner, screws '8 being employed in the present instance. At apoint adjacent one end of the plate and at a. suitable distance from theperiphery of the turntableis a post 9, to which is. attached ,one end ofa flat brake carrying spring 10. This spring, as stated,'being sccuredat one of its ends to the post 9, ex-

' tendstoward the periphery of the disk, and is-provided at its free endwith a socket 11 into which is fitted a brake shoe 12. the opposite endof the plate 7 and near the Near outer edge thereof is a verticallyextending pivotally mounted post 13 having keyed, or otherwise securedthereto a laterally extendingbrake actuating armlt. This arm beingspaced slightly above the upper surface of the plate 7, extendssubstantially the entire length thereof and is provided at its outer endwith a finger grip 15'. "Secured to the arm 14 at a point adjacent thefree end thereof, isa pair of upwardly extending arms or stops 16, and16', spacedslightly apart and which are adaptedto hold between them thebrake carrying spring 10. A keeper 17 is provided upon the plate 7,through which the arm 14 extends and which also acts as a stop for thespring 10 when' the same is in released position.

It is obvious from the foregoing description that when movement isimparted to the arm 14 'in a. direction toward the turntable of thegraphophone, a similar movement'is transmitted to the brake shoe 12through theaction'of the stop 16 upon the brake spring 10. and that whenthe. brake shoe contacts the periphery of the turntable, 'a bindingaction. will be brought about, holding the turntable against'anyfurtherrot-ation and which binding action will be relieved only when the arm 14has been returned to normal or inoperative position. When the arm 14-has been retracted, the action of the spring 10 against the stop 16 willhold the arm to open or retracted position.

For the purpose of automatically throwing the arm 14 to operativeposition, I se,-. cure uponthe' post 13 at a point above the arm 14, atripping arm 18. This triparm 18 is spaced above the brake actuating arma distance suitable to allow it 'to swing over the uppersurface of thegraphophone disk.

andis secured to' the post/13 by means-of a split sleeve 19 and'setscrew 20 in order that various radial adjustments may be n-iade." Anupturned finger 21 is provided, at the free end ofthe tri'p arm 18. andis adapted to be engaged by the 'ieproducer siipporting arm '3.

Through the adjusting feature of the arm 1S it will beseen-tha t at anypredetermined point on the record tli'eqmachinei may be autmnatieallystoppcd,-a nd'that'inttlie event. I

the operator drsi res"'toexchlsi'vely? man ually operate the stopmechanism,--the trip' arm 18 may be swung to inoperative position awayfrom the path of the t-rav'eling reproducer arm. p

The operation of the dcvicc'isas follows: bet-rip .arm 18 is adjusted tooperate the stop mechanism at "the termination of the spiral threadsupon the disk or, at any desired portion of the record. The turn tableis then set inmotion by releasing the brake shoe '12 fromengagerhent-withthe periphery thereof by moving the arm 14 to theposition shown in Fig.1, or more clearly illustrated in dotted lines in;Fig. 2. This releasing movement of the arm 14: simultaneously throws thetrip arm 18 to opera- ,tive position in-the path of the travelingreproducer arm'3 ,The4reproducer is then placed upon the disk andthe-spiral groove thereon gradually Imoves the arm 3" toward the centerof-the disk until, at the terminal of the groove on ata predeterminedpoint therein, the arm cont-aets the fingcr- 21'upon the arm 18, movingthe latter to the position shown in full lines Fig. 2.. This movement islikewise transmitted tothe arm 14 and the action of the stop 16 thereonupon the brake spring 10 causes the brake shoe-12 and without shock to.thelgraphophone pivoted post 13 tow'hieh the arms are secured isarranged at a distance from the axis of the table, greater than theradius of the largest disk adapted for use on the device. I

Having described my invention, what; I claim as new and desire to secureby Letters Patent is:

-1. In a device of the class described, the

casing, rotatable members and movable arm,

in combination with a post mounted upon said casing, a spring armsecuredat one end to said post, a brake shoe at the free end of said springarm, apivotally mounted brake actuatlng arm provided with a. )air ofstops engaging said spring arm, ant a trip arm connected to'said brakeactuating arm and having its free end arranged in the path of saidmovable arm, said trip arm being ar.-\

ranged above the plane of. the rotatable member and the rest of themechanism being arranged entirely below the plane of said rotatablemember, substantially as described. Y p

2. An attachment for a machlne having a casing, a rotatable member and amovable arm comprising a 'plate adapted to be secured. to the uppersurface of the-casing adjacentthe rotatable member, apost on said plate,a spring brake arm secured at one end to said post and extending towardthe periphery of the rotatable member, a pivotally mounted post adjacenttheopposite end of said plate, a brake aotuatingarln fixed to said postand-provided with stops for engagement with said brake arm, and a triparm secured at one end to said pivoted post and having a free endadapted to be arranged to lie in the path ofthe movable arm,substantially as described.

3. An attachment for a machine having a casing, a rotatable member, anda movable arm comprising a plate adapted to be secured to the casingadjacent the rotatable member,.a post on said plate, a spring brake armsecured at oneend .to said post, a pivotally mounted post adjacent theopposite end of said plate, a brake actuating arm fixed to said post andprovided. with stops for en gagement with said brake arm and'a trip armadjustably secured at one end to said pivoted post, the free end thereofbeing adapted to'be arranged to lie in the path of the movable armsubstantially as described.

. 4. An attachment for a machine having a casing, a rotatable member,and a movable arm comprising a plate adapted to be secured to the casingof the machine adjacent the rotatable member, a-post on said plate, aspring brake armfixed at oneend to said post and having a brake shoeatits free end .t eugagc said rotatable member, a brake actuat'in'g----arm pivotally mounted on said plate and. adapted to engage andoperate 'saidspring arm, a trip arm adjnstably connected to said brakeactuating arm, said spring arm and brake actuating arm lying in a planewholly below' the upper surface of the rotatable member and said triparm lying above the plane of the upper surface of said rotatable member,said trip arm be ing adapted to be actuated by the movablealum-substantially as-ib escribed. In testimony whereof I havesigned myname to this specification inthe presence of two subscribing witnesses.
